Elemental King/Queen summoning limits?

It is done on purpose, I think, forcing you to put a ton of gems at risk if you don't know the answer for sure: Is that third queen gone or not? If I ask, can I believe what the other players tell me?

{slaps self on head} Doh! I should have thought of that. For some silly reason it didn't even occur to me that someone else might cast one.

I really need to go back to playing MP games. In SP, by the time I can summon these things I have such a commanding lead on all the AIs it's pretty safe to assume none of them will "steal" one out from under me. In the game I'm playing now, I have Gale Gate running, plus 3 other globals, so I'm almost 100% sure that no AI is in a position to challenge me on summoning such things. But playing SP spoils me. The AIs just aren't aggressive enough or creative and sneaky, like humans are.

Thanks for pointing out my brain cramp.
